So, I'm trying to correct my technique and keeping my wrists straight to avoid pain. So far, I've managed to correct my right hand technique, but my left hand is annoying me. I've watched the "Safe Left Hand technique" video by Adam Neely, and I've been trying to follow the whole "thumb pointing at the headstock" position. It works flawlessly on the upper 4 strings, but it seems impossible to keep that position on the E and especially the B strings, thanks to the larger neck. It obviously gets worse on the lower frets. It seems like my wrist *has to* bend a little so I can nail any type of riff or scale. Am I doing something wrong, or is this innate to 5/6 string basses and larger necks? Because I'm checking some videos by some famous metal bassists and they all seem to bend their wrists like 45° or so when they're playing on that region, like on the thumbnails below.
